Sacrococcygeal giant cell tumor
The patient was complaining from low back pain and coccydynia long time ago. Initially, he was investigated by plain XR of the lumbosacral spine and coccyx. It suggested an erosive lesion of the sacrum. After that, the patient underwent pre and post contrast study of the lumbosacral spine and coccyx. It showed a definite sacrococcygeal destructive mass with a large soft tissue component that displaces the rectum. Lastly, CT is requested with IV and transrectal contrast to assess the relation of the large associated presacral mass with the pelvic structures especially the rectum. We can also trace the median and two lateral sacral arteries, the main arterial supply of the mass to ensure good hemostasis during surgical intervention. After resection and histopathological examination, it is proved to be a giant cell tumor of the sacrum.
